Messages Complain of Failure to Allocate I/O Resources
(CR 6984329)
Messages that complain about failures to allocate I/O resources might appear in POST and in
log files.
For example, you might see:
Sep 8 15:50:49 nsg14-28 kernel: PCI: Failed to allocate I/O resource
#2:20@0 for 0000:8d:00.0
Sep 8 15:50:49 nsg14-28 kernel: PCI: Failed to allocate I/O resource
#2:20@0 for 0000:8d:00.1
Workaround
BIOS tries to allocate I/O resources. If it is unable to allocate I/O resources successfully, it
displays error messages.
The OS might try as well. However if it tries, it fails and generates additional failure messages
because it uses the same method as BIOS. However, most drivers can manage this condition.
1. Usually, you can ignore these messages.
2. If you continue to experience I/O resource issues, see
I/O and Interrupt Resource Allocation
in the Sun Fire X4800 Server Installation Guide .
